Automatically Adjusting Country and Area Codes When Doing a Business Card or Telephone Number Exchange

ABSTRACT

A telephone number is automatically adjusted in the context a business card or other telephone number exchange. The country code, area code, or other prefix portion is added, removed, or modified based on a location associated with the telephone number and/or a location associated with the recipient. In one example, a sending device looks up location information by contacting the service provider, using locally-stored information, or otherwise, and, based on this information, includes au appropriate prefix. The sending device can also use a location associated with the recipient in determining an appropriate prefix or adjusting a received prefix, for example, based on the recipient&#39;s own telephone number. Adjustments to telephone numbers can also be made by recipient devices, intermediary devices, and any other devices that may be involved in the exchange of telephone numbers, business card information, or related activities, and in other contexts as well.

BACKGROUND

The present disclosure relates in general to communication between electronic devices and in particular to communicating phone number and other contact information between two electronic devices, such as a between two cellular telephones.

Mobile devices, including smart phones, personal digital assistants, and tablet computers, are rapidly becoming ubiquitous. These devices are increasing being used to make voice and video calls and to store contact information useful in establishing such calls. For example, a user of a smart phone device can typically save contact information records for themselves and others on the device. The contact information records include information about home addresses, business addresses, phone numbers, e-mail addresses, etc. and can be used to initiate direct communication with the associated contacts. For example, the smart phone user may open a contact and initiate a one touch command to call that contact's cellular telephone number. As another example, a user may click on a contact name displayed in a contact's listing and select to send an e-mail or text message to the selected contact.

Contact information records contain useful information about a person's contacts and can be shared with others in various ways. Contact information records can be sent via e-mail, Short Message Service (SMS), Bluetooth, WI-FI, using specific business card and contact tracking applications, and using other options. The vCard format is a file format for storing and exchanging electronic business cards that allows the vCards to be exchanged as attachments to e-mail messages, through instant messaging, and in other ways on the Internet. A first user may, for example, sends a text message with his or her vCard to a second user so that the second user can easily contact the first user. Once the second user has the vCard, the second user can use the telephone number and other contact information from the vCard to call or otherwise contact the first user. Phone numbers and other contact information used in vCards is, however, sometimes inaccurate, for example, in that location differences are not addressed. Dialing prefixes may be missing or inaccurate. This can result in failed call attempts and require significant effort on the part of the user to identify and enter an appropriate dialing prefix.

SUMMARY

Certain embodiments of the present invention provide techniques for automatically adjusting a telephone number when doing a business card or telephone number exchange. For example, the country code, area code, or other prefix portion of the telephone number may be added, removed, or modified based on a location associated with the telephone number and/or a location associated with the recipient. In the circumstance in which the telephone number is the number of the sending device, the sending device can look up location information by contacting the service provider, analyzing the local subscriber identification module (SIM) card, or otherwise, and, based on this information, include (or not include) an appropriate prefix. The sending device can also use a location associated with the recipient in determining an appropriate prefix, for example, based on the recipient's own telephone number or other recipient location identifying information. Adjustments to telephone numbers can also be made by recipient devices, intermediary devices, and any other devices that may be involved in the exchange of telephone numbers, business card information, or related activities. Telephone numbers can be adjusted in other contexts as well. For example, telephone numbers displayed on web pages, e-mails, or otherwise accessed from remote devices can be adjusted based on location information associated with the telephone number and/or location information associated with the recipient of the telephone number.

DETAILED DESCRIPTION

Certain embodiments of the present invention provide techniques for automatically adjusting a telephone number when doing a business card or telephone number exchange. For example, the country code, area code, or other prefix portion of the telephone number may be added, removed, or modified based on a location associated with the telephone number and/or a location associated with the recipient. In the circumstance in which the telephone number is the number of the sending device, the sending device can look up location information by contacting the service provider, analyzing the local SIM card, or otherwise, and, based on this information, include (or not include) an appropriate prefix. The sending device can also use a location associated with the recipient in determining an appropriate prefix, for example, based on the recipient's own telephone number or other recipient location identifying information. Adjustments to telephone numbers can also be made by recipient devices, intermediary devices, and any other devices that may be involved in the exchange of telephone numbers, business card information, or related activities. Telephone numbers can be adjusted in other contexts as well. For example, telephone numbers displayed on web pages, e-mails, or otherwise accessed from remote devices can be adjusted based on location information associated with the telephone number and/or location information associated with the recipient of the telephone number.

A device (“sending device”) sending a phone number to another device (“recipient”) can determine whether to modify a phone number and how the phone number should be modified based on location information associated with the phone Dumber. For example, consider a cellular telephone device (sending device A) sending cellular telephone device A's phone number to a recipient cellular telephone device (recipient device B). The sending device A has a telephone number from a service provider and calling that telephone number from elsewhere requires that a prefix be added to the beginning of the telephone number. When the sending device A determines to send the telephone number, it can determine an appropriate prefix to acid and modify the telephone number to be sent with to include that prefix. The appropriate country code, area code, and/or other appropriate prefix digits may be added to the telephone number. Modifying a telephone number may additionally or alternatively involve adding or modifying exit codes and/or entry codes, e.g., depending on whether the telephone numbers are associated with different counties. The recipient receives a number that requires little or no modification or manual lookup of dialing codes and the like prior to use.

The sending device A may determine a prefix based on its location. For example, the sending device A may communicate with a service provider to access sending device A's phone registration information. It may ping the service provider for location information so that it can receive or itself determine an appropriate prefix or request location information from another external source. In the circumstance of the service provider providing such information, the service provider may maintain a database of codes or other information to respond to such requests. In an alternative example, the sending device may retrieve location or prefix information from local storage or from an attached device or module such as on a subscriber identification module (SIM) card.

In modifying the phone number for sending to recipient B, sending device A may use information about the location of recipient device B. For example, sending device A is sending a phone number to a sending device B using short message service (SMS), the SMS messaging information known to sending device A (e.g., recipient device B's number) can be used to identify in which country and/or region the recipient's device is registered, e.g., registered on a home location register (HLR). For example, sending device A may identify that the recipient device B is registered in the United States and modify the telephone number being sent so that it includes an appropriate prefix for calling from the United States to the region in which sending device A's telephone number is registered. The recipient can then call the sending device's phone number with little or no modification of the telephone number and without having to look up dialing codes and the like.

In an alternative circumstance, a sending device can modify a telephone number being sent to a recipient even if the telephone number is not the telephone number of the sending device. The telephone number may be the telephone number of another device, for example. In such a circumstance, the sending device can obtain location and/or prefix information for the telephone number in various ways. In one example, the sending device pings the service provider the telephone number for location and/or prefix information. In another example, the sending device sends a message to the other device (e.g., using the telephone number) and the other device pings the service provider and returns the requested information to the sending device. As a specific example of this, if sending device A wants to send the telephone number of a third device C to recipient device B, sending device A can ask the third device C for its location and/or prefix information, the third device C can ping its service provider for the information and return that information to sending device A, and sending device A can then use the information to send a modified phone number of third device C to recipient device B.

In another example, location information for a telephone number is determined by identifying associated location information in other ways. For example, if the telephone number is a home number in a contact information record, the home address stored in the same record can be used to determine the location information and ultimately to determine an appropriate prefix or other modification.

Telephone number modification techniques can also be employed on recipient devices and intermediary devices. For example, a recipient may receive a telephone number and determine to add a prefix based on identification of a location associated with the received telephone number and/or the location associated with the recipient. As another example, a recipient may receive a telephone number with a prefix already included, determine that some or all of the prefix is unnecessary or requires modification based on identification of a location associated with the received telephone number and/or the location associated with the recipient, and modify the telephone number accordingly.

Techniques for automatically adjusting telephone numbers are particularly useful in the context of business card or vCard exchanges in which cellular phone, office phone, home phone, and other phone numbers are exchanged.

Telephone number modification techniques can also be employed in other contexts. For example, a telephone number can be modified when accessed while viewing a web page. As a specific example, if a user accesses a particular restaurant's web page (or a web page associated with any other real-world business) and selects the restaurant's phone number to retrieve or dial, an automatic process can identify an appropriate prefix to add to the number or other modification to the number based on the restaurant's location and/or the location associated with the device of the user that is viewing the webpage and requesting/calling the number. The restaurant's location and/or an appropriate prefix can be identified in various ways including, but not limited to, by identifying an Internet Protocol (IP) address associated with the web page, by identifying a tag or field on the web page that provides location and/or prefix information, or by another mechanism.

Another context in which automatic telephone number modification techniques is beneficial is where a single number is being distributed to multiple recipients. The number can be adjusted to target each of the particular recipients so that each recipient receives a number with an appropriate prefix or no prefix if none is needed. Thus, for example, a conference call organizer can send out a conference call dial-in number by simply sending a single number or reduced set of numbers that are automatically adjusted for each of the recipients.

The example embodiments described below relate to a configuration in which a telephone number is modified based on location and/or prefix information; however, it is to be understood that the techniques described herein can be applied equally to the other types of contact information that are location sensitive. For example, time zone information can be adjusted for a contact information record. Further, while the example embodiments described below make specific reference to a mobile device such as a mobile phone, it is to be understood that other types of devices can be substituted and that embodiments of the present invention can be applied in connection with providing contact information between any devices.

Further, the blocks need not correspond to physically distinct components. Blocks can be configured to perform various operations, e.g., by programming a processor or providing appropriate control circuitry, and various blocks might or might not be reconfigurable depending on how the initial configuration is obtained. Embodiments of the present invention can be realized in a variety of apparatus including electronic devices implemented using any combination of circuity and software.

FIG. 3 is a diagram of an exchange of a telephone number from one device 1 to another device 4, according to an embodiment of the present invention. In this example, device 1 is a cellular telephone device registered in India with a local telephone number of “25555555.” Device 1 determines to send its phone number to device 4. Prior to sending the number however, device 1 determines whether it should modify the phone number or not. In this example, device 1 recognizes that it is sending the phone number to device 2 via a United States registered telephone number and thus determines that it should append an appropriate prefix to the local telephone number.

To determine an appropriate prefix, device 1 communicates with service provider(s) 36. For example, device 1 may ping service provider(s) 36 for an appropriate county and area code corresponding to the location in which device 1 is registered in India. The service provider(s) 36 receiving such a request may obtain this information from database(s) 35 or the like and return an appropriate response to device 1. In an alternative embodiment, device 1 receives location information, e.g., identification of a geographic area that corresponds to the location in which device 1 is registered in India, and itself determines or identifies and appropriate prefix using that location information. In another embodiment, device 1 obtains an appropriate prefix without contacting service provider(s), for example, by retrieving such information locally from a SIM card 21 or the like.

Once device 1 has identified an appropriate prefix it prepends the prefix to the number and sends it to device 4. In this example, the message is sent through tower 3 through one or more intermediate networks to tower 6 from which it is distributed to device 4. The proposed number 31 sent includes the local number 34 “25555555,” a country code 32 “91,” and an area code 33 “79.” Entry or exit codes may also be appended in certain embodiments. Device 4 receives the proposed number 31 and stores it for later use. A user of computer device 4 can call device 1 without having to manually lookup and/or input the necessary country or area codes in this case.

FIG. 4 is a flow diagram of a process 40 that can be used by a device (e.g., device 1 of FIGS. 1-3) to modify a phone number when sending a contact information record to another device (e.g., device 4 of FIGS. 1 and 3) according to an embodiment of the present invention. Process 40 starts when a user or automated process initiates the transfer of a contact information record. At block 41, process 40 detects a request to send a contact information record from a first user to a second user. For example, a contacts managing application on a device may present contact records with a share option (e.g., provided via a contact sharing module 14 of FIG. 1) that allows a user to share a contact information record with other users. Process 40 may detect such an option being selected. As another example, a contact information may be received, for example, when another user sends a text message to the user of the device requesting contact information. Process 40 may detect such a request being received.

At block 42, process 40 determines a location associated with a phone number of the contact information record. The location associated with the contact information record may be determined by pinging a service provider to provide the location in which the phone number is registered. Alternatively, the location associated with the contact information record may be determined by identifying an associated information field in the contact information record. As a specific example, the process 40 may identify that the phone number is the “work” phone number of the contact record and identify the location as the “work” address listed in the contact information record. As another example, the location associated with the contact information record may be stored locally in memory or hardware on the device, for example, on an inserted SIM card and received from there. The location can be any information specific to the dialing prefix elements that may be required to call the device from remote locations. Thus, location information may identify a geographic address, geographic area, or may simply be the prefix itself since such a prefix is associated with a particular location.

At block 43, process 40 determines a location associated with the second user. This can be accomplished in various ways. For example, the location associated with the second user can be inferred from the information that will be used to send the contact information, e.g., the second user's own phone number prefix, e-mail address, contact information records, etc. Alternatively, the location associated with the second user can also be determined by contacting a service provider or other remote information source. The location can be any information that identifies a geographic address, geographic area, or may simply be a dialing prefix associated with a phone number of the second user since such a prefix is associated with a particular location.

At block 44, process 40 determines whether a modification of the telephone number is required. If not, the process 40 proceeds to block 46 to send the contact information record without modifying the phone number. If a modification of the phone number is required, however, the process first proceeds to block 45 to modify the phone number. Modifying the phone number may involve adding or deleting a country code, area code, entry code, exit code, or any other suitable modification that facilitates direct calling of the phone number by the second user who is to receive the modified phone number. Modifying a phone number may be accomplished via a contact adjusting module such as contact adjusting module 15 of FIG. 1. After the process 40 sends the contact information record in block 46 the process 40 ends.

FIG. 5 is a flow diagram of a process 50 that can be used by a device (e.g., device 1 of FIGS. 1-3) to modify a phone number when sending a contact information record to another device (e.g., device 4 of FIGS. 1 and 3) according to an embodiment of the present invention.

Process 50 starts when a user or automated process initiates the transfer of a contact information record. At block 51, process 50 determines a location associated with a phone number. The location associated with the phone number may be determined by pinging a service provider to provide the location in which the phone number is registered. Alternatively, the location associated with the contact information record may be determined by identifying an associated information field in a contact information record. As another example, the location associated with the phone number may be stored locally in memory or hardware on the device, for example, on an inserted SIM card and received from there. The location can be any information specific to the dialing prefix elements that may be required to call the device from remote locations. Thus, location information may identify a geographic address, geographic area, or may simply be the prefix itself since such a prefix is associated with a particular location.

At block 52, process 51 modifies the phone number with a dialing prefix based at least in part on the location associated with the phone number. Modifying the phone number may involve adding or deleting a country code, area code, entry code, exit code, or any other suitable modification that facilitates direct calling of the phone number.

At block 53, the process 53 involves sending the phone number for use on another device. The phone number can be sent by itself or as pail of a vCard or other contact information record. The phone number can be sent via a text message, e-mail message, or another other form of electronic transmission. The phone number can be sent via a telephone network, a data network, any other type of network, or through a combination of network types.

FIG. 6 is a flow diagram of a process that can be used by a device (e.g., device 4 of FIGS. 1 and 3) to modify a phone number at some point after receiving the phone number according to an embodiment of the present invention. At block 61, the process 60 receives a phone number with a dialing prefix included as sent from a sending phone device (e.g., from device 1 of FIGS. 1-3). This may occur in various circumstances. In one scenario, sending phone devices are configured to always send prefix information and the receiving device can remove unnecessary dialing prefix portions. In another scenario, some sending devices may send prefix information and other sending devices may not send prefix information with phone numbers.

At block 62, the process 60 identifies a location associated with the receiving phone device. While in the exemplary process 60 the location is identified after the receiving of the phone number, in other embodiments, it occurs prior to receiving the phone number. The location can be identified in various ways. For example, the location associated with the receiving phone device can be inferred or determined from information associated with the receiving phone device such as its phone number prefix, an associated e-mail address, contact information records associated with the receiving phone device, etc. Alternatively, the location associated with the receiving phone device can also be determined by contacting a service provider or other remote information source. The location can be any information that identifies a geographic address, geographic area, or may simply be a dialing prefix associated with a phone number of the receiving phone device since such a prefix is associated with a particular location.

At block 63, process 60 determines whether the prefix is required. If the prefix is required the process ends. If the full prefix is not required, at block 64, process 60 modifies the phone number. This may involve removing all or a portion of the prefix or otherwise changing the prefix. After modifying the phone number, process 60 ends.

FIG. 7 is a flow diagram of a process 70 that can be used by a device (e.g., any of devices 1, 4, 7, 8 of FIG. 1) to modify a phone number at some point after receiving the phone number according to an embodiment of the present invention. At block 71, the process 70 receives an identification of a phone number displayed on a web page. For example, a user viewing a restaurant's web page may identify and select to call a phone number of the restaurant displayed on the web page. As another example, a user viewing a web page listing contact information may select to import the listed contacts on the web page into contact information records on the user's local device.

At block 72, the process identifies a location associated with the phone number. The location can be identified in various ways. For example, the location can be determined using other information on the web page or in tags provided with the web page. Such tags, which may or may not be specialized tags specifically for the purpose of identifying phone number location information, for example, may identify the location associated with the phone number by providing a street address, identifying a geographic area, a dialing prefix, or other information. Alternatively, the location associated with the phone number can also be determined by contacting a service provider or other remote information source. Generally, the location can be any information that identifies a geographic address, geographic area, or may simply be a dialing prefix associated with a phone number of the phone device since such a prefix is associated with a particular location.

At block 73 the process determines whether a modification is required. If not, the process ends. If the a modification is required, at block 74, process 70 modifies the phone number. This may involve adding a prefix, removing all or a portion of the prefix, or otherwise changing the prefix. After modifying the phone number, process 70 ends.

Although embodiments described above make specific reference to a mobile device, those skilled in the art will appreciate that techniques described herein can be applied to any type of device including but not limited to mobile devices (e.g., smart phones, tablet computers, laptop computers, or the like) and stationary devices (e.g., desktop computer systems, servers, etc.). Likewise, an accessory can be any peripheral device suitable for operation with a given computer system or device.
